GUSTAV J AGENBURG, OF RYDBOHOLM, SWEDEN.

APPARATUS FOR DYEING.

SPECIFICATION forming part of Letters Patent No. 386,985, dated July 31,1888.

Application filed October 20, 1887. Serial No. 252,879.

(No model.) Patented in Germany January 5, 1887, No. 40,602; in

Sweden February 4, 1887, No. 916, and in Italy April 16, 1887, No.21,381.

To all whom it may concern:

Be it known that I, GUSTAV J AGENBURG, a subject of the King of Sweden,residing at the city of Rydbohohn, in the Kingdom of Sweden, haveinvented certain new and useful Improvements in the Process of andApparatus for Dyeing Loose Cotton, (for which have ob tained a patent inGermany, No. 40,602, dated January 5, 1887; in Italy, No. 21,381, datedApril 16, 1887, and in Sweden, No. 916, dated February 4, 1887,) ofwhich the following is a specification.

Heretofore it has been customary to boil loose cotton after the same hasbeen dyed, and this caused the cotton to lose all its plia' bility andto become still and brittle, so that it could not be spun on machinesusually used for spinning cotton, but only on machines used for spinningwool, and then only after saponified oil had been added.

The object of my invention is to provide a new and improved apparatusfor dyeing loose cotton,whereby the boiling of the cotton after thedyeing operation can be dispensed with.

The invention consists in the construction and combination of parts anddetails, as will be fully described and set forth hereinafter, and thenpointed out in the claim.

In the accompanying drawings, Figure 1 is a side view of my improvedapparatus for dyeing loose cotton. Fig. 2 is a plan view of the same.Fig. 3 is a cross-sectional view of the same. Fig. 4 is adetail view ofpart of one end of the apparatus, showing a modified construction.

Similar letters of' reference indicate corresponding parts.

The vat A has the usual shape of dyeingvats-namely, that of aparallelogram having rounded ends-and on the top of said vat thetransverse shafts D are mounted, that carry the agitating-arms E. A beltand pulleys and gearing are provided for the purpose of rotating theshafts and operating the arms or agitators E. A short distance above thefloor of the vat the perforated false bottom F is provided, and underthe same the suctionpipe G extends, which is connected with the rotaryor other pump H or with an injecting or like apparatus. Thedelivery-pipe J of the rial in the vat.

pump extends upward and is passed through the walls of the tank a shortdistance below the top edge, and on the end of said pipe a nozzle, J, orlike jetting device is secured.

A receptacle, K, containing the color-solution or concentrateddye-liquid is connected by the pipe L with the suction-pipe G of thepump, or said tank can be connected by the pipe L with thedelivery-pipeJ of the pump; but in this case said pipe J must beprovided with an enlargement, M, in which a number of horizontal screensare provided for the purpose of causing the concentrated color-solutionor dye liquid and the liquid passing through the delivery-pipe to 1111Kvery intimately.

The receptacle K is located above the level of the dye-liquor in the vatA for the purpose of preventing the liquor in the vat from rising intothe dye-receptacle K.

The material to be dyed is placed into the vat A, which is filled withwater or any suitable liquid or solution required for the dyeingprocess.

The liquid in the vat is drawn through the pipe G into the pump H andforced by the said pump through the pipe J back into the vat, whereby acontinuous circulation is kept up in the liquid in the vat.

The arms or agitators E agitate the mate The concentrated color-solutionor dye-liquid passes from the tank K through the pipe L into thesuction-pipe G, whereby the said color-solution is diluted, and in thisdiluted state ejected into the vat.

As the circulation of the liquid in the vat is continuous,the dilutedcolor-solution is continuously ejected into the vat until suchcolorsolution is exhausted.

As shown in Fig. 4, the color-solution may be conducted into thedeliverypipe of the pump, and is thus also diluted and ejected into thevat.

According to the nature of the color-solution or dye-liquid the loosecotton or other fibrous material can be dyed in a greater or less time.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In an apparatus for dyeing loose cotton or likematerial, the combination, with a vat, of lution is intimately mixedwith the dye-liquor, {O a suction-pipe for drawing theliquid from thesubstantially as herein shown and described. vat, a pump connected withsaid suction-pipe, In testimony whereofI havesigned my name adischargepipe connected with the pump to this specification in thepresence of two sub- 5 and terminating in the vat, and a receptaclescribing witnesses.

for receiving the concentrated dye solution, GUSTAV J AGENBURG. locatedabove the level of the dye-liquor in \Vitnesses: the vat and connectedoutside of the vat with NERE A. ELFWING,
